Please don't. I realize this was said tongue-in-cheek, but the ramifications of using local encryption without understanding it are large. You have to be willing to take on key management, or you risk losing every bit of data or being just as insecure as you would have been without encryption (with a slower computer as an added bonus).

Unfortunately, it takes at least a little buy-in from the user to make encryption work. We need better tools, for sure, but that final piece of holding the key needs to be taught and the responsibility accepted.
